What did you do?

const firstThread = computed(() => firstPostPage.value?.threads[0]); // https://github.com/n0099/open-tbm/blob/92fd7111a62c16f0f7ec29da5fae04a34532f1e2/fe/src/utils/post/seo/index.ts#L18
console.log(firstThread.value?.title);
//          ^ reporting violation of eslint rule `vue/no-ref-object-reactivity-loss`
(() => {
    const firstThreadTitle = computed(() => firstThread.value?.title); // https://github.com/n0099/open-tbm/blob/92fd7111a62c16f0f7ec29da5fae04a34532f1e2/fe/src/utils/post/seo/index.ts#L56
    console.log(firstThread.value?.title);
    //          ^ not reporting violation of eslint rule `vue/no-ref-object-reactivity-loss`
    console.log(firstThreadTitle.value);
    //          ^ reporting violation of eslint rule `vue/no-ref-object-reactivity-loss`
})();

What did you expect to happen?
firstThread.value?.title inside this IIFE should also report.

What actually happened?

Not reporting.

This also happens when the IIFE is a plain function outside the scope of firstThread being defined like:

const useOgImagePost = (firstThread: Ref<ResponsePage['threads'][number] | undefined>) => {
    console.log(firstThread.value?.title);
    //          ^ not reporting violation of eslint rule `vue/no-ref-object-reactivity-loss`
    console.log(firstThreadTitle.value);
    //          ^ reporting violation of eslint rule `vue/no-ref-object-reactivity-loss`
};
(() => {
    const firstThread = computed(() => firstPostPage.value?.threads[0]);
    useOgImagePost(firstThread);
})();
